The coin in question is part of the American Institute Medals series, specifically the Harkness medal, which was produced in the year 1858. This historic piece hails from the United States of America, although the specific mint where it was struck remains unknown. Notably, this coin falls under the denomination category of "Other / Varied," suggesting it may not conform to standard coin denominations. It was produced as a Mint Strike, indicating it was created using official minting techniques, which typically results in a high-quality finish. While the diameter, weight, and mintage information are listed as '0', this suggests that specific details about its physical characteristics or production run might be unavailable or not recorded, which is not uncommon for some older or less well-documented medals and tokens. As a type of coin, it is classified as a "Coin," and given its historical context and series, it likely holds significance for collectors interested in American numismatics, particularly those focused on medals and tokens issued by institutions. Overall, the Harkness medal serves as a unique artifact from the mid-19th century and represents a specialized aspect of American medallic art.
